Lemon Crumb Bars

Lemon Crumb Bars are a beloved American dessert, believed to have evolved from traditional lemon bars, which gained popularity in mid-20th century cookbooks. These bars combine the simplicity of shortbread crusts with the popularity of lemon custard pies. The “crumb” topping was a later addition, influenced by coffee cake-style toppings, to add texture and visual appeal
